11  Notes  New in this version
12  -----  -------------------
13  - I only tested it with:  
14          * RedHat Linux 6.[12] with 2.2.16.  - Fix POSIX compliance in timezone handling. Only putenv() is used now.
15          * cvs-1.10  
16          * rcs-5.7  - Fix branch-count when branches get folded.
17          * gd-1.3 (!)  
18    and have (yet) no clue wheter other systems will like my writing.  - Fix configure script to detect gd-2 problems (Thanks to Russell Yanofsky)
 - CvsGraph only generates (sort of) gifs at the moment because of an old  
   version of libgd. You are welcome to change this (shouldn't be too hard).

34    
35    NOTE:   The GD library is required for CvsGraph to function. Get it from
36            http://www.boutell.com, compile it and use either --with-gd-lib=DIR
37            and --with-gd-inc=DIR to specify its location. You might also have
38            to use --with-z-inc, --with-z-lib and --with-png-inc, --with-png-lib
39            for gd versions 1.6 and higher.
40            If you build with static libgd (i.e. libgd.a) and already have
41            libpng.so and/or libjpeg6b.so (i.e. dynamic), then you might want to
42            try to trick configure into adding these libs to the tests by adding
43            commandline options '--with-png-lib=.' and '--with-jpeg-lib=.'.
44            If you have linked libgd with freetype, then you might also need
45            either --with-freetype-lib or --with-freetype2-lib.
46    
47    There are often precompiled binaries for Linux, FreeBSD, NetBSD and Windows
48    (and probably other OSes too). Check your local mirror for details. I also have
49    some links on the homepage for precompiled binaries. Please do not complain to
50    me about these binaries.

83    Just to make it clear:  You cannot make images from a cvs-repository over the

85                            must be on a locally mounted filesystem. However, you
86                            can use cvsup or rsync to get a repository to your

100      If you are interested in tag-management with respect to the correct branch
101      information, then I suggest that you take a look at the contribution from
102      Henrik Carlqvist. He submitted some server-side scripts that can manage tags
103      in a better fashion than cvs on its own.

 - use autoconf  
 - use a newer version of libgd, or better, use ImageMagick for better control  
   over what is generated (also multiple output formats would be possible)  
 - find a way to use cvs directly instead of rcs (rlog) without the need for a  
   full checkout of the repository/module  
 - clean up the mess of finding revisions, tags and branches. The main branch  
   does not nessecarily start with revision 1.1
